Hello, Filipinos! Can I have some of your advice based on your experiences with Glock pistols? I would like to have your opinions and inputs ? What model of Glock would you recommed to me as a house gun and open carry, base on accuracy, reliability, durability, and stopping power ? Did you have any experiences of kabooms, malfunctions, or breachface failures with any of these two pistols ? 1) Glock 22 or Glock 21 ?
